Plugin compatibility JDK 1.8

[Maciej / Max]

Hello!
First of all, thank you for GWT Plugin! I got the following error :

\* What went wrong:
java.lang.UnsupportedClassVersionError: us/ascendtech/gwt/modern/GWTModernPlugin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes
 class file versions up to 52.0
> us/ascendtech/gwt/modern/GWTModernPlugin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

To my knowleadge, the plugin requires Java 11 but I use Java 8.

Am I right? Do you know how to make it work with Java 8?

Best regards,
Maciej

@MaciekKuna it's definitely supposed to be Java 8 compatible, are you using the most recent release?Also, it looks like some of our other libraries that you can just pull in using the plugin are not compatible, for example AG-Grid. Do you happen to be bringing in anything else?

For what it's worth, I was able to build a simple project without any add-ons using JDK 8.

[Payam Meyer]

Recompiled all other libraries and released version 0.4.17 with full JDK8 support.

@MaciekKuna please take a look and let us know if you run into any issues.

It's working fine. Thank you! Although I have some questions about configuration but I will create a new issue.
